8. Ubaldo Jimenez
Team(s): Colorado Rockies, Cleveland Indians
Career Era: 3.76
He only has four full MLB seasons under his belt, but Jimenez could make the list on the strength of his 2010 season alone. A 1.16 WHIP and 214 Ks pitching your home games in Denver will do that. Ubaldo's other seasons in Colorado were excellent by Coors Field standards, too; his 2011 season was a step back, but we'd still put our money on Cleveland being happy with their trade for him in five years.
